Allan Crossman comments that

in the 50/50 case, he has half as many successors as he would normally have. But it's not obvious why this should really trouble him.

Did everyone get what Crossman is saying? He is saying that it is not obvious to him why a MWI believer would hesitate particularly to play quantum Russian roulette with bullets in half of the chambers of the revolver!

Clearly then Crossman disagrees completely with Eliezer, who writes in this blog entry that Your decision theory should (almost always) be the same, whether you suppose that there is a 90% probability of something happening, or if it will happen in 9 out of 10 worlds.
